Abstract
Abstract Production data from a vanadium (V)-containing titaniferous magnetite (VTM) smelting blast furnace (BF) ironmaking plant and a V-recovering basic oxygen furnace (BOF) shop were collected over a period of 1 year. The corresponding thermodynamics was analyzed in terms of V reduction in the BF operation and V oxidation in the BOF operation. The thermodynamic calculations were performed using the software Multi-Phase Equilibrium (MPE), in which generalized central atom model was introduced into the description of molten slag and applied for the slag database. The effects of operating conditions on V distribution ratios between slag and hot metal/semi-steel were analyzed and compared with the plant data. The simulated results could reproduce the variation of V distribution ratios with slag temperature and composition and provide the guidance for operators to control V distribution behavior for the better process operation.
期刊介绍：
High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology. The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials at high temperatures. Occasionally, reviews of a specific topic are included. The journal also publishes special issues featuring ongoing research programs as well as symposia of high-temperature materials and processes, and other related research activities.
Emphasis is placed on the multi-disciplinary nature of high-temperature materials and processes for various materials in a variety of states. Such a nature of the journal will help readers who wish to become acquainted with related subjects by obtaining information of various aspects of high-temperature materials research. The increasing spread of information on these subjects will also help to shed light on relevant topics of high-temperature materials and processes outside of readers’ own core specialties.
